Questions about which diapers to buy?

[VAPC]

Im finally breaking in tomorrow and going to the store by myself to get some diapers tomorrow! I haven't had any for awhile cause I ran out of them,but they weren't mine. They were my grandmas and those were mckesson. Which are the best ones to get as far as adult disposables? I thought about getting goodnites,but I hear they fit some adults and the boys ones in l/xl are bigger than girls in that size.

Goodnites fit most adults rather tight but they are cheap.  Also Crinklz/Betterdry are well worth it.

I just bought some Rearz. Super absorbent but bulky and nosey.
